Heavyweight champ James "Iceman" Chambers (Michael Jai White) finds himself in jail once again in this sequel to the 2002 action classic. This time, though, the bars are in Russia -- at one of the country's most violent penitentiaries. Framed for a crime he didn't commit, the Iceman has no choice but to get back in the ring for a Russian Mafia-backed rumble with the big house's resident champ, Uri Boyka (Scott Adkins).
